THEFT-PREVENTING DEVICE.

hpplicationfiled September 20, 1924. Serial 1E0. 738,892.

This invention relates to thetl t preventing devices, and more particularly to bicycle locking mechanism, and has tor its primary object the provision of mechanism adapted to be adjustably supported upon the trame of the bicycle so that it may assume normal position at one side oi the vertical plane oil the wheel where it will not interlere with rotation of the latter, and which, when ad to justed to a locking position will project through the wheel parallel with its axis and effect a positive locked engagement there with.

A turther object 01 my invention is to provide mechanism oi this character which can. be applied to a bicycle :tran'ie of any well .lrnown construction without requiring alterations therein.

ll. further object of the invention is to provide locking mechanism which can be quickly adjusted to any one 031 the intended positions the occasion requires.

lt is one very important point of my invention to provide a device of this character which is simple and inexpensive of construe tion and adapted to be wholly carried by the frame of the bicycle at all times so that none of its essential adjuncts, except a con trolling hey would be carried on the person fl of the user.

In the drawing-'- l igure l is a view in side elevation of a portion of a bicycle trams showing my invention applied thereto and arranged in its normal position;

Figure 2 is a vertical section therethrough showing the device engaged with. the wheel to loch: same;

Figure 3 is a transverse section on the line 3-3 of Figure 1; and

Figure l is transverse section on the line el l ol' Figure 1.

l l hile I have described my invention for use primarily in connection with bicycles, :l this shall simply be taken as illustrative and it shall be understood that I am in no way to be limited in this respect.

In Figures l and 2 I show a bicycle frame 5 having a torlr 6 of usual well known con struction. On one of the side bars of the 'lorh; attached a frame member or sup port if", the same being clamped in position upon id sidebar as shown 3. The upper end o. the frame member is provided with a. as hi e loop ti which receives the bigbt pt 3 ll ed swinging element 1.0.

till

N orlnally, the swinging element 10 occupies the dotted line position shown in Figure 2. It is substantially parallel with the framemember 7, and dis desirable that the same be secured firmly thereagainst by a clamp. This clamp comprises a threaded stud 11 carried by the frame member 7 at a point between the ends thereof. Mounted on the stud. is a winged nut 12 which, when td]llSt6(l to the position shown in Figure 4, extends transversely of the element 10 and against the side bars or branches 13-13 thereof. The nut may be turned to assume a. vertical position between the bars 13-13 of said element 10 in order that the latter may be swung to a horizontal. tall line position shown in Figure 2.

i The side bars 13-13 are formed with ratchet surfaces 1 1 adapted to coact with a locking mechanism conventionally illustrated at 15. This lockingmechanism embodies a casing 16 having spaced apart openings 17 to slidably accommodate the bars 13-13 of said element 10. The locking mechanism is key controlled, and same is provided with an ad cutcheon 18 at one end.

lVhen the element 10 is in the dotted line position shown in Figure 2, the locking mechanism is secured in position upon the bars 1313. Nhen it is desired to move the element 10 to the full line position shown in Figure 2, the locking mechanism is removed. The element 10 is then swung inwardly and upwardly so as to extend entirely through the wheel 19, where its bars 13-43 will become correlated with the adjacent spokes of the wheel so as to prevent rotation of the latter. Then the element is thus adjusted, the locking mechanism is again adjusted on to the bars 13-13 as shown. The distance between the said bars 13-13 of the element 10 is suiticiently in excess of the width of the supporting member 7 so as to permit said bars 13 to freely pass against the sides of said supporting plate when moving the element to its adjusted position.

I claim:

A locking device for wheeled vehicles comprising a support adapted to be secured to a frame member 013' the vehicle and including an elongated flat plate. U -shapcd straps adapted to embrace the member, bolts extending through the plate and straps, and nuts on the bolts by means of which the plate is adapted to be clamped to the member, a hinge loop secured at one end and upon the outer side Ill) of the plate, a U-shaped locking element hinged in the loop and havingits arm portions provided with ratchet teeth a key controlled locking mechanism adapted to receive and be locked against removal from the arm port-ions, said element and mechanism normally occupying a position substantially parallel with and at the outer side of the plate.

a threaded stud projecting from the outer side of the plate, a winged nut threaded on the stud and adapted to engage the arms of the element to secure the element vand mecha- ,nism against movement on the ,plate, said element adapted to be swung inwardly to tioned position to thereby lock the wheel against rotation.
